.:ARINC429

Aeronautical Radio, Incorporated (ARINC) 429 Processing

process_raw (Level 1)

Purpose

Extracts ARINC 429 data from the SEA M300 data acquisition system file (*.sea) and saves the data to one or two output files.

Program Flow The process_raw.pro script calls the process_WMI.pro subroutine, which sorts the data based on data type and tag number. For data type 16 and tag numbers 12000 through 12022, call arinc.pro subroutine; for data type 16 and all other tag numbers call arinc429.pro. The arinc429.pro determines the aircraft ID associated with the data; if aircraft ID equals "FL-946", then go to arinc429_fl946.pro subroutine; otherwise convert the binary ARINC data to an integer and save to .serial.arinc429.raw and .serial.arinc429ch2.raw files. The arinc429_fl946.pro subroutine converts parameters with known conversion factors from digital data to floating-point type numbers and converts the other binary data to an integer and saves the data to the serial.arinc429.raw and .serial.arinc429ch2.raw files.
